How Exercise Boosts Memory
Huffington Post Blog - "The
scientific evidence is now clear. If you want to keep your mind
sharp as you age, you need to keep physically active. The
explanation has to do with the broad-reaching effects of
exercise on the chemistry, physiology and structure of the
awards first Certificate of Undergraduate Research
University of Illinois -
"Jennifer Merritt’s mind was racing as she prepared to graduate
last fall. She was working part-time in the lab of Professor
Justin Rhodes and trying to maintain high grades. She was
working hard to graduate in December, a semester early. She was
hoping her research experience would be an asset when she began
applying to jobs and graduate programs."

Finding Nemo lied to your kids, and they will do it
again in the sequel: Finding Dory!
The Fisheries Blog - The Disney film,
Finding Nemo, lied to your kids!
Disney would simply argue that they altered reality to create a
more entertaining storyline, but read below for the true story,
and you tell me which you think is a more entertaining.
Why I Think Better after I Exercise?
Scientific American - After being cooped
up inside all day, your afternoon stroll may leave you feeling
clearheaded. This sensation is not just in your mind. A growing
body of evidence suggests we think and learn better when we walk
or do another form of exercise. The reason for this phenomenon,
however, is not completely understood.
is a Spandrel? Explaining Evolutionary Adaptations and Side
Beckman Institute -
Neuroscientist and evolutionary biologist Justin Rhodes
explains the difference between traits that are the result of
evolutionary adaptation and others that are genetic spillovers.

Better Navigators Than Women, But Not Because of Evolution
Smithosian Blog - Some
stereotypes are based on nothing, but studies have verified one
generalization that we encounter in our daily lives: men tend to
be better navigators than women. Though the phenomenon appears
in a range of species, researchers don’t understand why it’s
Why Men Are Better Navigators Than Women: Adaptation or Side
Beckman Institute -
Neuroscientist Justin Rhodes explodes the myths behind why males
are better at navigation than females.
Exercise Protects the Elderly Against Brain Shrinkage
Discovery Fit & Health - "The brain shrinks as
we age, reducing memory and thinking abilities in the elderly
and researchers are constantly looking at ways to minimize this
atrophy of the brain."
Investigating Sex-Changing Clownfish (featuring Justin Rhodes)
Beckman Institute - Clownfish burst onto the
public scene nearly a decade ago with Disney-PIXAR's now classic
animated film "Finding Nemo." Perhaps unsurprisingly, the film
left out a very important part of the clownfish story -- that
clownfish can actually change their sex in response to their
social environment. Beckman Institute neuroscientist Justin
Rhodes examines how the clownfish brain orchestrates this
amazing, gender-bending swap.
Q&A: The key to a better brain is exercise
SmartPlanet - "Keeping your brain sharp
may not, in fact, be about doing more challenging crossword
puzzles or engaging in specialized digital games or relearning
the quadratic equation. What can make all the difference is
something more fun and far less intuitive: Toss a frisbee,
dance, run, skip. Get active."
How Exercise Could Lead to a Better Brain
New York Times - "For more than a decade,
neuroscientists and physiologists have been gathering evidence
of the beneficial relationship between exercise and brainpower.
But the newest findings make it clear that this isn’t just a
relationship; it is the relationship."
How Exercise Can Prime the Brain for Addiction
New York Times - "Statistically, people who
exercise are much less likely than inactive people to abuse
drugs or alcohol. But can exercise help curb addictions? Some
research shows that exercise may stimulate reward centers in the
brain, helping to ease cravings for drugs or other substances.
But according to an eye-opening new study of cocaine-addicted
mice, dedicated exercise may in some cases make it even harder
to break an addiction."
Timing Critical for Using Exercise
as Drug Addiction Intervention
Beckman News - "Could exercise have beneficial
effects for treating drug addiction, such as have been shown for
disease prevention and improving cognitive health?"
New neurons reduce drug-seeking behavior
Nature News Blog - "Now, research presented at
this week's annual meeting of the Society for Neuroscience in
Washington DC shows that increasing the brain’s ability to
generate new neurons decreases drug-seeking behaviours in
rodents. The implication is that therapies that boost
neurogenesis may one day help drug addicts on the long road to

"Justin Rhodes is a neuroscience researcher who created a
new marine biology laboratory at the Beckman Institute that will
use clownfish and their ability to change sex in order to gain
insights into brain plasticity."

Running to Distraction
ScienceNow - "Die-hard joggers now have a new worry. If they're anything like
running-addicted mice, they may want to ease off their training
regimen to stay sharp. Even though running makes mice sprout new
neurons, running compulsively makes them slower learners."
Rhodes Probes Causal Mechanisms of Voluntary Behaviors
Beckman News -
"Rhodes’ research as part of the
NeuroTech group seeks to find the causal mechanisms that
underlie motivational behaviors. One of his research projects
was among the first to find that motivation for beneficial
behaviors such as exercise and motivation for detrimental
behaviors like alcoholism and drug addiction could have the same
